ac> Hi folks.  How do I directly access memory in a DOS application (ie. 
ac> _osmode == DOS_MODE) compiled with EMX 0.9b / GCC 2.7.2?  Specifically, I

ac> (color screen text display), and so forth.  Thanks.

With either Watcom or EMX (can't remember), to access screen memory,
you just go:

char *p = 0xb8000;

*p = 'A';
*(p+1) = 'A';

etc.  I believe different DOS extenders do it differently.

BFN.  Paul.
